And this, on turbo engines:
"Kratos is getting its cues from a US Air Force (USAF) vision of developing a fleet of low-cost missiles and attritable UAVs that can overwhelm, evade or outdistance sophisticated and far-reaching Chinese and Russian air defence systems," writes Garrett Reim in Flight Global, an industry trade publication, earlier this year.
The problem these companies are seeking to solve is that the electric propulsion systems currently in use on many fixed wing drones are simply too heavy for long-range flights, particularly with heavy payloads. Pound for pound, liquid fuel carries about 50 times more energy than batteries.
'Many fixed wing drones using electric' never really happened, we already have miniature combustion motors available for cheap. Hobbyists have had turbo fan for quite sometime, at a few grand in price.
